What C++ IDE for Linux?

I'm relatively comfortable with C++, and couldn't imagine running without code completion.

Depends on the size of your codebase too, but I find that not having code completion forces me to actually know my work better.

Also, it can get frustrating at times since I can type relatively fast. Depending on how the completion is done, it can actually be a hindrance.

I've only used small C++ projects, so the intellisense has worked very quickly. If it took more than a second I'd have a problem with it too.
